摘要： A process device wireless adapter (300, 600, 700, 800) includes a wireless communications module (310, 602, 702), a metallic housing (302, 606), and an antenna (320, 604, 826). The wireless communications module (310, 602, 702) is configured to communicatively couple to a process device (350) and to a wireless receiver (502). The metallic housing (302, 606) surrounds the wireless communication module (310, 602, 702) and has a first end and a second end. The first end is configured to attach to the process device (350). In one embodiment, a metallic shield (608, 708) contacts the housing (302, 606) second end such that the metallic shield (608, 708) and the housing (302, 606) form a substantially continuous conductive surface. The antenna (320, 604, 826) is communicatively coupled to the wireless communication module (310, 602, 702) and separated from the wireless communication module (310, 602, 702) by the metallic shield (608, 708). Preferably, the wireless communications module (310, 602, 702) illustratively includes a printed circuit board that has a length that is greater than its width.

摘要： A field device system (12) for use in an industrial process includes a field device (14) configured to couple to the industrial process and monitor or control the industrial process. The field device provides a temperature control signal output related to a temperature of the field device. A heater (24) coupled to the field device (14) heats the field device (14) in response to the temperature control signal.

摘要： A field device for use in an industrial process control or monitoring system connects to a two-wire process control loop. The loop carries data and provides power to the field device. RF circuitry in the field device is provided for radio frequency communication. A power supply powers the RF circuitry using power received from the two-wire process control loop.
